Palau is one of the world's premier diving and marine destinations — the Rock Islands Southern Lagoon is a UNESCO World Heritage Site, and its underwater biodiversity is staggering. But Palau's marine environment demands respect and awareness. Here's what you need to know to stay safe.
Diving Safety
Palau is famous for current diving — many of the best sites (Blue Corner, Blue Holes, Peleliu Wall) involve drift dives with strong currents that attract large marine life. This creates world-class encounters with sharks, manta rays, and massive schools of fish — but it also means:
- Minimum certification: Most dive operators require Advanced Open Water certification or equivalent. Some sites require 50+ logged dives.
- Current awareness: Currents can shift rapidly. Always carry a surface marker buoy (SMB) and whistle. Listen carefully to dive briefings.
- Reef hooks: Palau popularized the reef hook — a metal hook on a line that attaches to dead coral, letting you hang in the current and watch the show. Learn to use it before your first current dive.
- Deep dives: Several signature sites (Blue Holes, Chandelier Cave) involve depths of 25–40 meters. Monitor your air and bottom time carefully. Dive computers are essential.
- Decompression chamber: Palau has a hyperbaric chamber at Belau National Hospital in Koror. Know its location.
Jellyfish Lake
Jellyfish Lake (Ongeim'l Tketau) is Palau's most famous natural wonder — a marine lake containing millions of golden jellyfish that have lost their stinging ability over thousands of years of isolation. Swimming among them is surreal and safe, with a few caveats:
- No scuba diving allowed — snorkeling only. The lake's deeper layers contain toxic hydrogen sulfide.
- No fins allowed — to protect the jellyfish. Swim gently.
- The lake was closed 2016–2018 when jellyfish populations crashed (likely due to El Niño warming). Populations have recovered, but the experience depends on natural cycles.
- The hike in is steep — about 15 minutes over rocky terrain. Wear sturdy water shoes.
Sun and Heat
Palau sits 7 degrees north of the equator — UV radiation is intense year-round:
- SPF 50+ reef-safe sunscreen is now legally required in Palau — the country banned reef-toxic sunscreens in 2020, the first nation to do so.
- Rash guards provide the best sun protection for water activities.
- Hydrate constantly — humidity averages 80%+.
General Safety
- Crime: Palau is very safe. Violent crime against visitors is nearly unheard of. Standard precautions for valuables apply.
- Roads: Koror's main roads are paved. Some Rock Island access roads are unpaved. Drive carefully at night — no street lights outside town.
- Health: No malaria. Dengue fever is possible — use repellent. Medical facilities in Koror are basic — serious injuries may require evacuation to Guam, Manila, or Hawaii.
- Travel insurance: Absolutely essential — include dive coverage and medical evacuation.
The Palau Pledge
Palau created the world's first eco-pledge stamped into passports — visitors commit to act responsibly toward the environment. This isn't ceremonial — Palau enforces marine conservation laws aggressively. Don't touch coral, don't chase marine life, don't take shells, and follow your guide's instructions.
Palau is one of the safest and most rewarding destinations in the Pacific — but its marine environment demands respect, proper training, and good judgment. Come prepared, dive within your limits, and you'll have the underwater experience of a lifetime.
